OperationShort-Circuit ProtectedCurrent Mode Operation for Excellent Line and LoadTransient ResponseConstant Frequency Operation: 2.25MHzLow Dropout Buck Operation: 100% Duty CycleSmall, Thermally Enhanced, 10-Lead (3mm × 3mm) DFN Package典型应用典型应用描述The synchronous buck converter provides a high efficiency output, typically 90%, capable of providing up to 500mA of continuous output current while switching at 2.25MHz, allowing the use of small surface mount inductors and capacitors. A mode-select pin allows Burst Mode operation to be enabled for higher effi ciency at light load currents, or disabled for lower noise, constant frequency operation.
